Review on 🐶 Hartz UltraGuard Flea & Tick Collar for Dogs and Puppies -- 7 Months Protection, White, Up to 15-Inch Neck Size by Chris Edgerton

Absolutely nothing I dislike about these flea collars. I have 5 Boston Terriers and they all wear them. I use a puppy collar for her. I don't leave my dogs outside all the time, running in tall grass etc. They do the job I need them to do. They don't seem to last the full 7 months but that doesn't bother me. I change them all at the same time when they need it. Never had a problem with them, unlike one of the expensive collars that burned and scratched the neck of one of my dogs (used the right size collar for each rep). Now she can't wear collars at all.
